利用JT-60 U的快速时间分辨诊断技术研究了I型ELM引起的离子温度（ΔTi/Ti）、电子温度（ΔTe/Te）、基座储能（ΔWELM/Wped）和环向旋转速度（Vt）的相对变化。在等离子体电流的方向上，发现在ELM后的Vt的增加。发现Vt的恢复比Wdia、Te和Ti的恢复快。ΔTi/Ti可以大于ΔTe/Te。
We investigated the relative change in ion temperature (ΔTi/Ti), electron temperature (ΔTe/Te), pedestal stored energy (ΔWELM/Wped), and toroidal rotation velocity (Vt) due to type-I ELMs using diagnostics with fast temporal resolution in JT-60U. The increase in Vt was found in the direction of the plasma current right after the ELM. The recovery of Vt was found to be faster than that of Wdia, Te and Ti. It is also found that ΔTi/Ti can be larger than ΔTe/Te.
